Product information

Description

The CNC NV821563 miniature circuit breaker is a reliable 3-pole electrical protection device designed to safeguard residential, commercial, and industrial electrical installations. Rated at 40A with a C-curve tripping characteristic and a 6kA breaking capacity, this device effectively protects circuits against overloads and short circuits, ensuring safe power distribution and equipment longevity. It features flame retardant construction with high temperature and impact resistance, alongside anti-mistake contact terminal blocks and clear contact position indication where red indicates closed and green indicates opened.

Advantages

This miniature circuit breaker provides robust dual protection against both electrical overloads and short circuits to prevent damage to connected wiring and equipment. Its durable housing offers excellent flame retardancy, high temperature resistance, and impact resistance for enhanced operational safety. The device supports flexible connection from both the top and bottom using cables or pin-type busbars, accommodating wire cross-sectional areas up to 25mm². With a mechanical life of 20000 cycles and an electrical life of 8000 cycles, it ensures long-term dependable performance.

Suitable for

  • Residential electrical distribution panels
  • Commercial building sub-circuits
  • Light industrial power control systems
  • Protecting three-phase electrical loads up to 40A

When it may not be suitable

This circuit breaker is not suitable for main incoming supplies requiring currents higher than 40A or applications exceeding its 6kA breaking capacity. It should not be installed in outdoor environments without an appropriate weatherproof enclosure, as it features an IP20 safety class.

Key specifications

  • Number of poles: 3
  • Rated current: 40 A
  • Tripping curve: C
  • Rated voltage: AC 400 V
  • Rated breaking capacity: 6000 A
  • Mechanical life: 20000 operations
  • Electrical life: 8000 operations
  • Ingress protection: IP20
  • Mounting: 35mm DIN rail EN 60715

How to use

Installation should be performed exclusively by a qualified electrician in compliance with local electrical codes and standards. The circuit breaker is designed for quick and secure mounting onto a standard 35mm DIN rail using its fast clip device. Connect incoming and outgoing conductors to the designated terminals, ensuring proper tightening to accommodate wire sizes up to 25mm². Verify that the terminal connections are secure and check the visual contact position indicator before energizing the circuit.

What to consider before purchase

  • Verify that the 40A rated current matches your load requirements
  • Confirm that your electrical system voltage aligns with AC 400 V
  • Check available space in your distribution board for the 3-pole module dimensions
  • Ensure operating temperatures will remain within the -5°C to +40°C range

Always disconnect power to the distribution board before attempting any installation, inspection, or maintenance work. Periodically check terminal connections for tightness to maintain optimal electrical contact.

Product comparison

The CNC NV821563 miniature circuit breaker is compared with similar protection devices from CNC and Schelinger. All these models share core safety characteristics: a C-curve tripping characteristic, a 6kA breaking capacity, and a design suited for residential, commercial, or industrial electrical installations. The main differences lie in the number of poles, current ratings, and the VDE certification of alternative models.

⚙️ The specifications comparison outlines the differences between the reviewed device and alternative options regarding pole count, current load, and design structure.

Use caseRecommended productWhy
Protection of a three-phase power line at 40ACNC NV821563Ideally matches pole count and current rating requirements for three-phase loads and distribution boards.
Protection of a single-phase line at 40ACNC NV821464Single-pole design is optimal for switching the phase conductor in single-phase electrical grids.
Protection of lower-load lines (20A or 32A)CNC NV821532 or CNC NV821556Lower current ratings ensure proper protection for thinner cables and lower-power equipment.
Three-phase grid requiring independent VDE certificationSchelinger A02-G8-3P-C40Offers matching electrical parameters with additional quality confirmation according to VDE standards.
Three-phase grid requiring neutral disconnectionCNC NV821631Four-pole construction allows simultaneous disconnection of three phases and the neutral wire.
The CNC NV821563 miniature circuit breaker differs from alternative models by combining a 3-pole configuration and a 40A rating with a standard 6kA breaking capacity. It is best suited for installation in three-phase distribution panels within residential, commercial, and industrial facilities where reliable overload and short-circuit protection for medium-power equipment is required. A buyer should prefer this model if the project specifically demands 3-pole switching at 40A without requiring neutral disconnection or alternative current ratings.
